[Samba] Samba 3.0 + LDAP userPassword -> sambaNTPassword manual sync?

[Cybr0t McWhulf]

First, the software:
Samba 3.0.0
OpenLDAP 2.0.27
nssldap / pam_ldap
Redhat 9

This may be more of a question for the OpenLDAP mailing list.. but does
anyone know of a method (perhaps using slappasswd?) to hand-sync userPassword
attributes to sambaNTPassword attributes?

Deploying Samba 3.0 as pdc pretty soon, used Migration Tools on the mail
server soon, and I'd really like to be able to tell people to log in using
their mail credentials, as opposed to a generic password that they might
not ever change, resulting in the ever-unfun activity of tracking people
down and berating them until they change it  (This was hard enough the
first two times).

Any suggestions or advice would be greatly appreciated, and as always
great thanks to the Samba team for their terrific work.
